摘　　要：针对通孔插装技术的电路板缺陷焊点检测不能实体在线标注的问题,应某电子企业生产流水线的要求,设计了一种电路板缺陷焊点自动标识装置控制系统。系统以STM32F103VET6为控制核心,与作为上位机的AOI检测设备进行通信,获取缺陷焊点坐标值,控制多机构动作,实现缺陷焊点自动标识功能。测试表明,该系统能够准确无误地对缺陷焊点进行在线标识,直观易辨,完全满足企业生产需求,具有良好的应用前景。On the printed circuit board with through-hole mounting technology,defective solder joints can＇t be marked on-line. To deal with this problem,a control system of automatic marking defective solder joints device was designed according to the requirement of an electronics enterprise production Line. The system was based on STM32F103VET6 control core. It communicates with the automatic optical inspection（AOI）device which operates as the host computer, getting the coordinate value of defective solder joints,and then controls different mechanisms to mark the defective solder joints automatically. The tests results shows that the control system can mark the defective solder joints on- line accurately and clearly. This design meets the demand of enterprise production completely,processing broad ap- plication prospect.
